Specification of Letters Patent.

EYELET-SETTING TooL.

Application filed September 22, 1914. Serial No. 862,920.

To all whom it may concern Be it known that I, WILLIAM J. TATRO, a-

citizen of the United States, residing at Brockton, in the county ofPlymouth and State of Massachusetts, have" invented certain Improvementsin Eyelet-Setting Tools, of which the following description, in connection with the accompanying drawings; is a specification, likereference characters on the drawings indicating like parts in theseveral figures.

The present invention relates to tools for setting blind or invisibleeyelets in sheet materiahsuch, for example, as the uppers of boots andshoes.

It has been the practice to employ in power eyeleting machines atoolhaving an outwardly projecting shoulder of relatively small diameterupon which the upsetting surface is formed, the construction being suchthat the upsetting surface may be passed through the outer part of theshoe upper and located substantially between the outer and linin parts.y

One object 0 the present invention is to provide for such a tool meansfor holding the work in a fiat condition adjacent to the eyelet beingset and for yieldingly opposing the'thrust imparted to it by the eyeletas the latter is insertedfrom the opposite side of the work. "This isimportant because otherwise the advancing end of the eyelet barrel 4would push the material of the work ahead facilitatesthe operation etahigh speed of an eyeleting machine equippe'd w th the set-ftingiool'inthat it reduces the lnterval,'dur-' 1n -rnaterial whichstretches (ream forced upon the upsetting tool. 'Asherein shown'thedes1red"r'esults are i of it and force the lining upon the-tool so farthat the eyelet barrel would be clenched without passing through thelining. This is particularly the case in dealing with light y' as it isattained by arrangin upon the upsetting tool a washer of rub r-or otherresilient material with its workfengagmg surface disposed in thevicinity fl the upsetting surface of the tool.

In addition to the funiitions'above mentioned a'device of this characteracts also as a stripper tending to press the work toward the end of..thesetting tool after the setting-pressure has been released. This whichthe tool prpgects into theworki he construction an-- Patented Mayaa-iaie.

novel tool of this invention will behest unof the cooperatingsettingtools showing their positions in a shoe upper at the com pletionof the setting operation.

As shown in Fig. l the upsetting tool comthe upsetting tool; Fig. 2 is asectional view i prises a cylindrical body portion 10' shouldered"at'its lower end and provided with a concentric projecting portion 12.The portion 12 is, in turn shouldered to form the curved upsettingsurface 14; against which the end of the eyelet barrel is clenched inthe setting operation. Below the upsetting surface 14 is a portion; 16of the tool which is tapered somewhat toward the end of the tool. In theembodiment of the invention 'herein shown the upsettingtool is utilizedalso as a punch and accordingly thefltoolis provided with a centrallongitudinal bore and the lower edge of the portion 16 is shaped forpunching. In case, it is desired: to use the tool in a machine equippedwith separate punching mecha'- nism; the u setting tool may be solid andits end shape to enter the punched hole and to pass. through both partsof the work.

Surrounding the portion 12 and held thereon by fr ction is a washer 18ofleather, rub

her or other suitable resilient material. The upper surface of thewasher 18bears against the lower surface ofthe body. ortion 10 surfaceof the washer is disposed above' the upsetting surface l tby' a distancesome The upsetting tool-is intended to be usedin. coiiperationvwith aneyelet arrying or insertingset of the usual construction, such a setbeing indicated byfreference character'20 in Fig. 2. This tool'isjshapedat its upper end to receive the flange of-the eyelet and providedwith acenter spindle21 which Y. oa hs i 01 whilethe lower or 'wor engaging 1,

holds the eyelet in 1 place preliminarily to V the setting operation andthen yields. down; jwai'dly "into the set 20 when, it encounters -n 1'a11nerj{ofusingthe";

theiupstti gl h j ,upper to be crowded over barrel shall pass throughhole formed by diameter than "the portions of the tool immediately abovethe punching end thereof the material of the upper will stretchsufficiently to permit the outer part 22 of the shoulder 14.- uponthe-portion 12 of the tool. An eyelet is supplied to the set 20 and,with the two tools arranged in alinement, the set 20 is elevated toinsert the eyelet barrel through the lining portions 24 and 25 of theupper. In this' operation the set. 20 and the eyelet carried therebytend to force the work upwardlyupon the upsetting tool crowded above theupsetting shoulder 14 so that the eyelet would be clenched below thelining portion. It might happen also that the material .onone side ofthe tool would be crowded upwardly past the upsetting shoulder and inthis case part of the eyelet barrel would be clenched properly above thelining and the remainder would be clenehedwithin or below the lining. Asabove intimated the provision of the resilient washer 18 obviates suchdifliculties for the washer engages the outer portion 22 of the upperover a considerable area adjacent to the upsetting surface and holdsthis portion in a fiat condition and consequently the lining portions 24and 25 will also be held in a flat condition. Moreover the washeryieldingly opposes the upward movement of the work upon the upsettingtool and so insures that the end of the eyelet the lining and'not merelypush the work ahead of it. In eyeleting work of different thicknesses itis conteniplated that washers dimensions will be placed in position uponthe upsetting tool.

Having thus described my invention, I

.claim as'newand desire to secure by Letters Patent of the UnitedStates:

1. A tool for setting blind or invisible eyelets, having a body portionterminating in a rigid shoulder, a portion projecting therefrom andbeing "provided with an outwardly extending upsetting shoulder, and awasher of resilient material surrounding the projecting portion andhaving its work the upsetting tool is of less the upsetting engagingsurface located adjacent to the upsetting shoulder.

2. A tool for setting blind or invisible eyelets, having its end shapedto pass through both the lining and the outer parts of an upper, aconcentric upsetting shoulder of small diameter located above the end ofthe tool so that it may be carried through one part of the upper, awasher of resilient material located mainly above the upsettingshoulder, and a washer supporting surface formed by part of the tool.

3. A tool for settingblind or invisible eyelets, having an outwardlyextending shoulder shaped to constitute an upsetting surface, and a'rubber washer so located as to act as a stripper tending to push thework from the upsetting surface after the clenching operation.

4. A tool for setting blind or invisible eyelets, ha.ving.an upsettingshoulder-of relatively small diameter constructed and arranged to becarried substantially through one part of an upper, and a resilientmemher having substantially greater width than and, if this movementwere not opposed, the lining portions 24 and 25 might also be by thepunching end of the tool in the upper of tWo superposed layers of sheetmaterial, and a work engaging device perforated to fit upon the toolabove the upsetting shoulder and having a lower work engaging face whichis normally disposed above the upsetting shoulder and is capableofadjustment to accommodate material of different thicknesses.

6. A tool for setting blind or invisible eyelets, comprising a bodyportion termi-- nating in a shoulder, a portion of reduced diameterprojecting from said shoulder and having formed therein an upsettingshoulder, whereby said reduced portion and upof the appropriatetwoisubscribing witnesses.

setting shoulder may be passed through one part of a shoe upper, and awasher of resilient material having a Work engaging surface disposednormally above the pe-' riphe'ry of the upsettin shoulder.'

In testimony whereo I have signed my name to this specification in thepresence of WILLIAM J. TATRO.
